COMBINED THRASHING-MACHINE AND CLOVER-HULLE R.

SPECIFICATION forming part of Letters Patent No. 230,562, dated July2'7, 1880. Application filed A hi 21880. (No model.) Q

. T all whom it may concern Be it known that I, HENRY A. MILLER, ofFindlay, in the county of Hancock and State of Ohio, have inventedcertainnew and use ful Improvements in Combined Thrashing-Machine andOlover-Huller and I do hereby declare that the following is a full,clear, -and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which- Figure l is a plan or top view, theroof of the machine having been removed; and Fig. 2 is a longitudinalvertical section.

Similar letters of reference indicate corresponding parts in both thefigures.

lhe object of this invention is to produce a thrashing-machine for wheatand other grain which is adapted also to be used as a clover thrasherand huller 5 and it consists in the construction and combination ofparts, as hereinafter full y described,and particularly pointed out inthe claim.

In the drawings, A is the frame of the machine, in one end of which isthe throat B, through which the grain or clover (as the case may be)which is to be thrashed is fed. Back of the throat B is the concave O,in which runs the thrashing-cylind erD, of the usual construction.

E is the shaking pan or frame, which is suspended, by suitably-arrangedhangers c c, inside of the machine, back of the concave andthrashing-cylinder, and has a perforated bottom, beneath which, andaffixed removably upon the sides of the shaking-frame, is a sheetmetalplate, E, corresponding in length and width to the shaker E, of which itforms a detachable part.

F is the straw carrier and separator, which, in like manner as theshaker E, is suspended by hangers f f, and has a perforated bottom,underneath which is a permanent sheet-metal floor or plate, E, which issecured upon and forms a part of the carrier-frame. The shaker Eoverlaps with its rear end the straw carrier and separator F F, and areciprocating or vibrating motion is imparted to the shaker 2nd carrierby pitmen a b and a rotating shaft,

0, in such a manner that they will reciprocate simultaneously againsteach other.

If it is desired to use the machine for thrashing wheat, the grain isseparated from the straw, after it has passed the thrashing-cylinder, bythe perforated shaker E and carrier F, by their vibratory motions, thegrain falling down through the perforations, in the first instance, uponthe fioor E, which vibrates with the shaker and delivers it (the grain)upon the forward end of the separator and carrier F, where it fallsthrough the holes down upon the imperforate bottom F, and is dropped atthe rear end of this into the vibrating shoe G, upon the riddles ofwhich it is subjected to the blast from the fan H in the usual manner.Such of the grain as is not separated from the straw during its passageover the vibrating shaker E is mixed with the straw, received upon theseparator and carrier F, by the vibrationsof which it is further sifted,being caught, as it drops through the perforations, upon the imperforatefloor F and stepped chute I, by both of which it is conveyed down intothe shoe, while the straw is delivered to the stacker at the end of thecarrier F in the upper rear corner of the machine.

When, on the other hand, the machine is to be used for thrashing andhulling clover-seed, the detachable shaker-floor E is removed and theriddles in the vibrating shoe G are changed for othersof a finer mesh.The clover is fed through the throat B to the thrashing-cylinder in likemanner as the wheat but as, after thrashing, it leaves the concave andis received upon the vibrating perforated shaker E, the

- seed drops down through the perforations upon a rigid horizontal flooror diaphragm, K, over which travels, in the direction of the arrows, aslatted apron, L, suspended between and operated by the rollers l l l.As the seed is received upon floor K it is carried by the slats of theapron L toward the forward part of the machine and discharged at the endof the floor down into the concave M of the hulling-cylinder N. As,after hulling, the seed leaves the cylinder it is received upon aninclined'plane or floor, K, where it again meets the slatted apron L onits return trip from the lowermost roller, 1, and is by this aproncarried up the inclined plane to its upper end, Where it (the seed) isdropped into the riddles of the shaking shoe and cleaned by the blastfrom the fanning-mill in like manner as the wheat.

To facilitate the operation of thiashing, a beating-cylinder armed withteeth may be placed back of the thrashing-cylinder in the upper part ofthe machine; but, as this is a common expedient in threshing-machines, Ihave not shown it in the drawings.

The several cylinders and rollers, with theirshafts, are rotated bypulleys and endless belts or intermeshing cog-wheels in a manner wellunderstood, and which does not, therefore, require illustration and itis obvious that when the machine is used for thrashing wheat the bandsfor operating the hullingcylinder N and endless slatted apron L may beunshipped, as these only operate when the machine is used for hullingclover.
